OSTEOGENESIS STIMULATOR WITH DIGITAL SIGNAL PROCESSING
摘要
A stimulator and a method for electrical stimulation of bone to promote osteogenesis is disclosed in which surface electrodes positioned around an incision site transmit an interferential current that has a base medium frequency alternating current between 1K-20KHz. A digital signal processor generates a sine-wave-like waveform from a pulse generator which after further processing is used to generate two circuits for use in producing the interferential current. The effective area of stimulation is controlled by placement of electrodes and electrode orientation. Amplitude modulation of electrical circuits created at the electrode placements also augments the effective area of stimulation.
